Using oVirt 4.3.7 - testing on 2 diff environments.
So editing via UI and waiting some days, or using the below process both
still don't work.
What seems to happen is it does update the running HE with the new RAM
amount while booted, but the OVF is not updating because as soon as the
VM reboots its back to original value of 4GB, so the increase is only
applicable for that current running session.
When editing in the UI it seems it does not save, I can go straight back
into the VM info or edit screen and it has instantly reverted back to
4096mb even though the VM itself now has 8 (trying to change from 4->8).
When saving, even the log says "Hotset memory: changed the amount of
memory on VM HostedEngine from 4096 to 4096" so it seems the system is
actively limiting my ability to update the HE - this happens both in
global maintenance mode and no maintenance mode.
On a customers cluster - I am getting a lot of EngineBadHealth and the
HA agent is constantly moving it around on me, I fear because of RAM, so
I'd like the OVF to update so on fresh boot it can keep a new RAM config.
Any help appreciated.

Which oVirt version are you using?
From 4.2 you don't need to wait, you should be able to update the HE
memory via UI:
1. Enable global maintenance
2. Change HE VM memory via UI
3. On the HE, run: # hosted-engine --vm-shutdown
4. Wait for HE VM to be down: # hosted-engine --vm-status
5. Start HE VM: # hosted-engine --vm-start
6. Disable global maintenance

Have you tried to add more RAM via UI and leave the VM for a
day /even 2/ for the OVF to be updated ?
I know that there is an option to force faster OVF updates , but
it's still slower than the defined frequency.
